Relationship of insecticide tolerance to esterase enzyme activity in Aphis pomi and Aphis spiraecola (Hemiptera: Aphididae).

Journal of economic entomology, 2010
Green apple aphid, Aphis pomi De Geer, and Aphis spiraecola Patch (both Hemiptera: Aphididae), are sympatric aphid species that are pests of apples (Malus spp.) and other crops. A. spiraecola has been shown to be significantly more tolerant to several insecticides compared with A. pomi.

Widespread resistance of the apple aphid Aphis spiraecola to pyrethroids in China

Pesticide Biochemistry and Physiology
The apple aphid, Aphis spiraecola, is an important pest in apple orchards. Pyrethroids had been widely used for the control of apple aphid. To verify the resistance level of A. spiraecola against pyrethroid insecticides, 35 field populations from main apple-producing areas of China were collected, and the susceptibility to type I and type II ...

The Natural Enemies of the Citrus Aphid, Aphis Spiraecola (Patch)

Journal of Economic Entomology, 1925
This is a preliminary report on the natural enemies of Aphis spiraecola in Florida. The citrus area of the state was injured by the aphid to the extent of about four million dollars during 1924. No true parasites were observed by the writer, but several predaceous insects are of some value in checking the aphid.

Capacity assessment of Myzus persicae, Aphis gossypii and Aphis spiraecola (Hemiptera: Aphididae) to acquire and retain PVYNTN in Tunisia

Arthropod-Plant Interactions, 2017
The study was carried out to investigate the ability of three aphids, Myzus persicae, Aphis gossypii and Aphis spiraecola, to acquire and retain the Potato Virus Y (PVY) isolate, PVYNTN. Tobacco plants, Nicotiana tabacum var. Xanthi, were used as test plant for the virus inoculation and aphid acquisition.

Effect of Aphis spiraecola and A. pomi (Homoptera: Aphididae) on the growth of young apple trees

Crop Protection, 1993
Abstract One-year-old ‘Redchief Delicious’ apple trees grown in pots in an unheated greenhouse with screened ends were inoculated during the summer with either spirea aphid, Aphis spiraecola Patch or apple aphid, A. pomi DeGeer. Photosynthesis and greenness (the extent of chlorophyll colour) of apple leaves were reduced by increasing accumulated ...

Sex Pheromone of Aphis spiraecola (Homoptera: Aphididae): Composition and Circadian Rhythm in Release

Journal of Asia-Pacific Entomology, 2003
Abstract Aphis spiraecola (Patch) virginiparae were reared for 3 generations on the dropwort, Oenathe javanica DC, under low temperature (15°C) and short days (10L:14D) for artificial induction of sexual forms (Hong and Boo, 1998). These oviparae, artificially induced in the third generation in the laboratory, showed a typical behavior of ...

The Apple Aphid and the Citrus Aphid: Aphis Pomi Degeer and A. Spiraecola Patch

Journal of Economic Entomology, 1929
Various entomologists. publishing on the citrus aphid, use the name Aphis Spiraecola . For the convenience of those who wish to retain this name in economic literature, certain food plants, previously recorded by the writer for A. pomi, are here indicated for the race overwintering on Spiraea and commonly known as the citrus aphid.

Overexpression of UDP-glycosyltransferase UGT344B29 and UGT344B30 involved in lambda-cyhalothrin resistance in Aphis spiraecola

Pesticide Biochemistry and Physiology
UDP-glucuronosyltransferases (UGTs) catalyze the conjugation of diverse small lipophilic compounds with sugars to form glycosides, playing a critical role in xenobiotic detoxification in insects. In this study, a lambda-cyhalothrin resistant strain (LC-R) of Aphis spiraecola was constructed through continuous selection with lambda-cyhalothrin ...
